Other claims from this paper (19)
- Observation Msitu Zanzibar had greater yield than Aipin Valenca and Amani 4026/16.
- Observation Aipin Valenca yielded more than Amani 4026/16.
- Association Varietal yield differences were associated with bulking rate.
- Intervention effect Higher plant density increased tuber yield per hectare, with a greater mean increase in Aipin Valenca than the other two varieties.
- Observation Calculated optimum density for maximum yield in Msitu Zanzibar was 6·7 plants/m 2.
- Observation Calculated optimum density for maximum yield in Aipin Valenca was 6·4 plants/m 2.
- Observation Calculated optimum density for maximum yield in Amani 4026/16 was 5·6 plants/m 2.
- Association Spacing effects on tuber yield were associated with bulking rate differences.
- Observation Aipin Valenca was usually taller than the other varieties.
- Intervention effect Increasing density generally increased plant height.
- Observation Final total dry matter per area was greater in Aipin Valenca and Msitu Zanzibar than Amani 4026/16.
- Intervention effect Increasing density increased dry matter per area except in Amani 4026/16.
- Observation Dry matter per plant was greatest in Msitu Zanzibar, followed by Aipin Valenca and Amani 4026/16.
- Intervention effect Dry weight per plant increased as plant density decreased in all three varieties.
- Observation Aipin Valenca and Msitu Zanzibar allocated more dry matter to root tubers than Amani 4026/16.
- Intervention effect Increasing density generally decreased dry matter allocation to root tubers.
- Intervention effect Higher density increased crop growth rate but decreased net assimilation and relative growth rates.
- Intervention effect Higher density decreased net assimilation and relative growth rates.
- Association Bulking rate was positively related to root tuber yield.
